icare4depression: effectiveness of a blended cognitive-behavioral therapy in routine practice

Conditions: Major Depression

Summary: the main objective of this research project is to implement and evaluate the clinical effectiveness and cost-effectiveness of a blended cognitive-behavioral therapy (bcbt) in routine practice, comparing it with treatment as usual (tau). this research project includes a pilot study and a randomized clinical trial (rct). the pilot study main objective is to adapt the bcbt based on moodbuster, an internet-based treatment platform developed by the ict4depression consortium (inesc-tec, vrije universiteit and university of limerick), to the portuguese population. more specifically, this pilot study intends: (1) to detect problems and refine procedures, establishing a definitive portuguese version of the blended treatment; (2) to assess clinical effectiveness (non-controlled), estimating effect sizes at the end of the treatment and follow-up; (3) to assess patients' satisfaction and personal views concerning their process of change; (4) to develop dynamic models of the individual trajectories during treatment based on ecological momentary assessments. the pilot study will involve the participation of psychologists trained in bcbt and 20 participants diagnosed with major depression and willing to use the moodbuster system. the rct is composed by two arms (an experimental condition and a control condition) and it will be implemented in routine practice. in the experimental condition, the patients diagnosed with major depression will receive a treatment that integrates face-to-face cognitive-behavioral sessions with online sessions available through moodbuster system (bcbt). in the control condition, patients diagnosed with major depression will receive tau that consists in routine care that patients receive in primary care. the rct will involve the participation of family doctors and psychologists working in routine practice. one-hundred patients will be recruited and randomized in the two conditions: 50 patients for bcbt condition and 50 patients for tau condition. the main objectives are: (1) to assess the clinical effectiveness of bcbt and compare it with tau in routine practice; (2) to estimate and compare cost-effectiveness of both treatments; (3) to assess patients' and clinicians' satisfaction with the bcbt and tau; (4) to refine the previous models of individual trajectories and to assess differential effects on different patient clusters; (5) to establish guidelines for using bcbt within portuguese routine practice services.

internet-based interventions in depression have emerged over the last decades to improve the access to effective treatments. despite the increasing relevance of these treatments, empirical evidence is still needed to demonstrate their clinical and cost-effectiveness in different healthcare contexts. the present study represents an extension to the portuguese context of the original trial developed by the ecompared consortium. the overall project involves a pilot study and a randomized clinical trial (rct). the pilot study main objective is to adapt the bcbt based on moodbuster, an internet-based treatment platform developed by the ict4depression consortium (inesc-tec, vrije universiteit and university of limerick), to the portuguese population. more specifically, this pilot study intends: (1) to detect problems and refine procedures, establishing a definitive portuguese version of the blended treatment; (2) to assess clinical effectiveness (non-controlled), estimating effect sizes at the end of the treatment and follow-up; (3) to assess patients' satisfaction and personal views concerning their process of change; (4) to develop dynamic models of the individual trajectories during treatment based on ecological momentary assessments (ema). the pilot study will involve the participation of psychologists trained in bcbt and 20 participants diagnosed with major depression and willing to use the moodbuster system. the assessment protocol will be implemented at the baseline, during therapeutic sessions, 16 weeks and 26 weeks after baseline and it is composed by several measures that evaluate depressive symptoms, anxiety symptoms, distress, quality of life, working alliance, treatment credibility and expectancy, treatment satisfaction and system usability. moreover, the ema concerning mood, sleep quality, anxiety and other emotional states will be collected in a daily basis before, during and after the treatment. the intervention protocol includes ten face-to-face cognitive-behavioral sessions combined with nine online sessions based on the self-help treatment modules of the moodbuster (psychoeducation, exercise therapy, behavioral activation, problem solving, cognitive restructuring and relapse prevention) delivered over a period of 16 weeks. the rct is composed by two arms (an experimental condition and a control condition) and it will be implemented in routine practice. in the experimental condition, the patients diagnosed with major depression will receive a treatment that integrates face-to-face cognitive-behavioral sessions with online sessions available through moodbuster system (bcbt). in the control condition, patients diagnosed with major depression will receive tau that consists in routine care that patients receive in primary care. the rct will involve the participation of family doctors and psychologists working in routine practice. one-hundred patients will be recruited and randomized in the two conditions: 50 patients for bcbt condition and 50 patients for tau condition. the main objectives are: (1) to assess the clinical effectiveness of bcbt and compare it with tau in routine practice; (2) to estimate and compare cost-effectiveness of both treatments; (3) to assess patients' and clinicians' satisfaction with the bcbt and tau; (4) to refine the previous models of individual trajectories and to assess differential effects on different patient clusters; (5) to establish guidelines for using bcbt within portuguese routine practice services. the assessment protocol will be implemented at the baseline, during therapeutic sessions, 16 weeks, 26 and 52 weeks after baseline and it is composed by several measures that evaluate depressive symptoms, anxiety symptoms, distress, quality of life, working alliance, treatment credibility and expectancy, treatment satisfaction, system usability and cost-effectiveness. moreover, the ema concerning mood, sleep quality, anxiety and other emotional states will be collected in a daily basis before, during and after the treatment. the intervention protocol includes ten face-to-face cognitive-behavioral sessions combined with nine online sessions based on the self-help treatment modules of the moodbuster (psychoeducation, exercise therapy, behavioral activation, problem solving, cognitive restructuring and relapse prevention) delivered over a period of 16 weeks.
